To all 'whom t may concern I Be it known that l', Funnrnien Kennin, a citizen of the United States, und e residentv of the city of New York., borough or Eroolrlyn9 in the coimty r inge @tete ci? New Yorin here iuvt u, new und lin-- proved luet-Collector7 of Yl the 'Collotw ing is a full, clear, and enact deeeription.

'lfhis invention relates to dust colle ting devicee and has for an object the provision of an'iinproved construction which does not require any power vfor operation but ruil. collect end discharge :it predeternnned points dust forced therein. i

Another object in View is to provide dust 'eways end collecting sections whereby the duet and air muy freely enter und by the changing or" direction seperated so that the puritied or clean air may be discl'ierged out et one point and the dust out et' another point.

A still further object in View is to provide e collector in which the torce of the dustluden oir may be varied in order toretuivi the movement thereof sulliciently for coueing e precipitation oi the dust.

ln they accompanying drawings:

Figure 1 is a. longitudinal vertical section through e collector disclosing un embodiment oi the invention, the seine be taken approximately on .line 1-1 or '3. r Fig. 2 is e section through 2 2.

Fig. 3.. is t section through 3---3- s Referring; to the accompanying tun of any oesired kind which is designed to drew in dust from any source and force the through pipe 2 .into the drum. ot the coilector: rllhe intention is to use the collector in connection with Hour mills, furnaces or with any other devine desired. in @our mills and other blames are z li'rudy in use-Which drive the dust out of the wey and to collectors of different kinds under some circumstances. The fen 1 is of the type just described and is utilized for drawing in the dust from the liour mill or eisewli-ere no cording to Where the colleetcr 1s urranged.

. The dust of different character collected is discharged into drum 3 in horizontal div-- rection and is caused to circulate :iround seid drum for almost e complete revolution.. it is iinellv discharged out the opening; el@ into beveled gear 24 chamber 5 and from thence into chemberA of the casing 7. Drum 3 is pro'vided With u. plurality ol apertures 8 in the bottom through which the heavy mutter may fell directly into the chamber 6 while the lighter 60 metter is carried around to the discharge opening" shown particulrly in Fig.

y2 e well 9 is provided which causes the air ,12 und strike against the cone bottom 13 so that the dust is precipitated, The remaining dust end air pass upwzirdly through a' pluiulity of pipes ,14 and eventually out opening 15 into the pipe 16. ln changing 30 the direction ut opening l5 some ofthe dust is caused to precipitate and thev remaining duet is caused to precipitate by striking the bottles 17 und 18 in pipe 1G. A dust discimrge damper 19 provided in each of the 85 pipes 167 seid dempers being usually held uien only sufliciently 'fur to allow the -dust to pues therethrough. rihe damper 19 may be held in any miius'sted position by the handle Q0. which in turn nmy be held by any 99 desired hind oi catch or may be provided with notches so :is toovcrlep part of the pipe 1G.

@lily tour pines 14: are shown and four pipes but it will be evident that a greater niunber @n it ilY l ed u lesser number may he nee-:l zlimr' from the spirit of 'the invention, its is evident, part of the air and dust n'iired therewith will enter the clizunber 13 und will attempt to move upwardly through thc oir pipe 10. The dust will be precipitated to the bottom of cone 13 while striking against the cone member 11 und :Liso by reirson of the coneshirped valve bei' is provided with a threaded lend 22 for accorninodziting the threads of bar 2". A

is connected with bar 23 so as to rotate the bur when the beveled gear is roteted by the driving gear 25, which drivand rovided with means for oneratinon bv 'the hand. When it is found that dust is passing upwardly through the air p'ipe 10 jbar 26 is rotated for closing to a greater or less extent the valve 21 until onlyv air passes up this pipe.

.It is of course evident that if too much air and dust are forced in by fan 1 for the particular sized collector the parts will not properly operate and some of the dust will escape through the air pipe 10 and some through the pipe 16. In a case of this kind the fan must have the speed thereof reduced or more than one collector connect- As shown particularly in Fig. 1, the cone bottom 13 has a discharge pipe 27 for discharging the dust, said pipe 27 having a valve or damper 28 which may be maintained open or closed by a handle 29. Preterablyl the damper 28 is held partially closed so as to allow the dust to pass therethrough but not any air. It will of course be noted that the dust Iis not very closelyv packed and there is some air mixed therewith as the same enters the pipe 27, but this air is ermitted to escape out the pipe A30 which is provided with a damper 31, said damper being usually slightly open. As shown in Fig. 2, a plurality of shutter dain- 'pers 32 are provided on top of drum 3,

the same being adjusted as may be desired for allowing some-"of the air to escape at this' point, or may be adjusted for maintaining the drum closed. f

In operation, when it is desired to use the dust collector at any place,pas for instance, in a flour mill, the usual.y exhaust fan in the mill isconnected up to the/pipe 2, as shown in Fig. 2, and as the fan collects the dust and forces .it through pipe 2 so that part Will pass through aperture S and part Will pass through the openi-ng l into chamber 5 and then into chamber It will be observed that chamber 5 is larger than the opening 4 and, consequently, the pressure on the air will be suddenly reduced, whereby a precipitation et the dust will be made. rIhe air passing from chamber to chamber 6 will be further reduced under pressure, thus allowing a further precipitation. The precipitated dust will gravitatc `into the bottom 13 while the air and unprecipitated dustl'will pass either into the air pipe 10 or out the pipes 14, where the remaining dust is collected or caused to be precipitated. It is evident that the collected dust may be discharged directly downwardly -from the collector or may be discharged into pipes which will guide the dustto a convenient discharge point,

What I claim is: y

1. In a dust collector of the character described, a casing, a drum arranged at the upper part of said easing provided with an intake opening and a discharge opening discharging into said casing,' said drum being formed with an annular passageway and ay wall for directing the air and dust to said discharge openii'ig, a collecting cone arranged at the bottom of said casing, a collecting cone arranged above the first nientioned cone, an air pipe extending from the second mentioned cone, and a valve member in said second mentioned cone i'or shutting ofi' the dust while permitting the air to escape therethrough.
